The skin has several important functions such as excretion, absorption, and sensation. Excretion involves removing waste products from the body through sweat and sebum production. Absorption refers to the ability of the skin to absorb certain substances, such as medications or nutrients. Sensation allows us to feel sensations such as touch, pressure, pain, and temperature. While the skin does have a role in pigmentation, it is not one of its primary functions. Pigmentation is controlled by melanin in the skin, which gives skin its color and helps to protect against UV radiation. Therefore, pigmentation is not considered a main function of the skin.
